Ibisobanuro
TPS54320 niyuzuye-17-V, 3-Asynchronous intambwe-hasi ihinduranya igashyirwa mubikorwa bito bito binyuze mumikorere ihanitse kandi ihuriweho na MOSFETs yo hejuru kandi yo hepfo.Ibindi byo kuzigama umwanya bigerwaho binyuze muburyo bugezweho bwo kugenzura, bigabanya kubara ibice, na
guhitamo inshuro nyinshi zo guhinduranya, kugabanya ikirenge cya inductor.Ibisohoka voltage itangira-igenzurwa na SS / TR pin yemerera gukora nkumuriro w'amashanyarazi wenyine cyangwa mugihe cyo gukurikirana.Imbaraga zikurikirana nazo zirashoboka mugushiraho neza uburyo bushoboka hamwe no gufungura imiyoboro yamazi meza.Umuzenguruko ukurikije ukwezi kugarukira kuruhande rwo hejuru FET irinda igikoresho mugihe kirenze urugero kandi ikongerwaho nimbaraga zo hasi zishakisha imipaka irinda guhunga.Kurinda Hiccup biterwa iyo ibintu birenze urugero byakomeje igihe kirenze igihe cyagenwe.Guhagarika amashyuza bihagarika igice mugihe ubushyuhe bwo gupfa burenze ubushyuhe bwo guhagarika ubushyuhe.TPS54320 iraboneka muri 14-pin, 3,5-mm × 3,5-mm VQFN, ipaki yongerewe imbaraga.Ibikoresho byamakuru PART NUMBER PACKAGE BODY SIZE (NOM) TPS54320 VQFN (14) 3.50 mm × 3.50 mm Kubipaki byose biboneka, reba kuri gutegekwa kwinyongera kumpera yurupapuro rwamakuru.
